It is peace of mind—knowing that when I have a tight deadline, I don’t have to worry about my machine working. That’s a big deal. Or I know if I run into a problem, I can call you guys. I have full confidence in BOXX and that’s a huge deal because you don’t needed added stress on top of everything else and deadlines are always shifting.
